Question Installing RTLinux in RHEL 4 - WS

Hi everybody,

I am trying to install RTLinux on RHEL 4 - WS. I have downloaded the prepatched version of rtlinux for 2.6.9 kernel from the fsmlab's rtlinuxfree website.

my fs -
/dev/hda8 /
/dev/hda6 /boot
/dev/hda7 swap

I then ran the following commands -
make 0=/usr/src/linux-2.6.9-rtfree/kernel config
make 0=/usr/src/linux-2.6.9-rtfree/kernel
make 0=/usr/src/linux-2.6.9-rtfree/kernel modules_install install

I checked the /boot partition and found the newly compiled kernel and the initrd image in the /boot partition alongwith the other 2.6.9-11 kernel of rhel 4. The initrd and vmlinuz are pointing towards the new initrd and vmlinux image.
Also the grub.conf was also modified to include the entry for the new kernel... the entried been similar to the other kernel entry...

after rebooting i am able to boot from the other kernel but i am not able to boot to the rtlinux kernel... it gives the foll error -

Kernel Panic - Not Syncing : unable to find root fs on block (0,0)

i tried giving the root= option in the kernel command with root=/dev/hda8
again the same error...

i tried giving the root=/dev/hda6 option... it gave a new error...
kernel panic - not syncin - init not found : try using the init= option

If somebody can help me it would be great
